Michael Weiner’s primary duty in the MLBPA to be its Executive Director. But since his elevation to that post in 2009, he has maintained his former title as general counsel as well, operating in both capacities. Today the MLBPA announced that it has elevated its Chief Labor Counsel Dave Prouty to the position of general counsel, leaving Weiner as Executive Director.

There was no reason given for the move. It’s probably worth noting, though, that Weiner has been fighting cancer since last summer. Some reporters have mentioned on Twitter that there may be a further update on that today. Here’s hoping that this change in management structure is not due to his health turning for the worse.
